Dude...I live in the middle of Chicago in an apartment on the top floor of the building.
If I go to check my mail, I can run into as many as 15 neighbors. I could wear the shirt inside until it was time to walk the dog. Then I'd have to change shirts. Why? I just glanced out my window and there are five people within 20-yards of my apartment building's front door right now. I'm not trying to be a party pooper, it's just not something I'd wear or use, period.
Instead I bought a Brownells branded shop apron.
